1 Claim. (01. I'll-s29) the under side of said'iender This inventionrelates to a signal device for vehicles, which automatically lightsandflthef H lighted part moves when an electrical circuit is closed, asby applying a brake pedal.

' I am well aware thatothers have provided wigwag light signals forvehicles whichautomatically light and move when a brake pedal or otheragency is applied; but they have notachieved commercial success to anyextent be-- viceso simpleiinfconstructionzand operationthat be attached'to any type "of automobile-without the'services of a skilled mechanic.A further object is to provide means to protectthe' motor for saiddevice from rain, snow or other efiects of inclement weather; sothat itmay operate under the most unfavorable conditions and when it is neededthe most. a

The foregoing and other objects which appearas the nature of "the.invention is better understood, may be accomplished'by a construetion,combination and operative arrangement .of

. as to render it susceptible to various changes and modifications, and,therefore," I am not to be limited to said disclosure; but am entitledto all such-changes therefrom as fall within the scope of my claim.
